Abstract
A developing apparatus, includes: a developer bearing member that is rotatable; an moving member configured to move the magnetic developer carried on the developer bearing member before the magnetic developer is restricted by a restricting member, the moving member being rotatable and brought into contact with a surface of the developer bearing member; and a control portion, wherein, at a contact position between the developer bearing member and the moving member, assuming that a moving speed vector of a surface of the developer bearing member is taken as R and a moving speed vector of a surface of the moving member is taken as r, the control portion controls rotational operation of the developer bearing member and the moving member such that a direction of a vector R−r during image formation and a direction of a vector R−r during non-image formation be opposite to each other.
